What happened?

Hi! I downloaded Vampirism for 1.20.1 in a server with friends, back when we played in 1.17.1 we didn't had any problem when pressing V to drink blood from animals but now every time (at least for me) i press V the game frozes and kicks me out of the server and i can't find any solution :/
Edit: My friend doesn't have these crashes but she mentions the V button doesn't work and won't suck blood neither, tried changing the keys but same issue

can you share the whole crash-report, this is just an excerpt

Updates over the issue: Now it only did not affect the blood feed system, me and my friend found a Hunters fortress/camp (the big ones) and started kicking us out the server with the message "Internal Server Error" i checked the new log and the previous one and they seem to have the same problem, my apologies btw over closing and opening this 😭 Github on phone is weird
(Triend unstalling the mod from the server and download it again but it didn't work)

can you share the whole crash-report, this is just an excerpt

Sure! Y copied from there all the way bellow (i hope is the right one-)
